ZTV is a TV studio in the Yu-Gi-Oh! manga.
The director from the channel tried making a false documentary on bullying, Caught on Camera: School Violence for Survival Morning, in which he got his assistant director, Fujita to bully Yugi. As punishment, Dark Yugi inflicted a Penalty Game onto the director, causing him to effectively go blind.
Jonouchi took part in the game show "Get the Million" on ZTV. The producer tried to rig the competition so that Jonouchi couldn't win the ¥1,000,000, but Dark Yugi spilled paint on the buttons, making him unable to tell which button rigs the wheel. Although Jonouchi won, the check turned out to be worthless after the studio went out of business, since Dark Yugi inflicted another Penalty Game onto the producer, causing him to go insane and insultingly demand money from viewers on live camera, which led to a complete drop in ratings.
